MAX931CSA

Comparators Overview

The MAX931CSA is a single-supply, micropower comparator featuring an integrated voltage reference. It operates within a supply voltage range of 2.5V to 11V and delivers CMOS or TTL compatible outputs. The device exhibits a propagation delay of 12µs and maintains extremely low power consumption with a supply current of less than 4µA across the full temperature range. Packaged in an 8-pin SOIC format, it is designed for applications requiring minimal energy usage.

Comparators Feature Summary

• Integrates a high-accuracy voltage reference for simplified circuit design
• Supports both CMOS and TTL output logic levels
• Optimized for ultra-low power operation in battery-driven systems

Comparators Applications

• Main power voltage monitoring circuits
• Backup battery schemes with delay functions
• Adjustable LNB power supplies compliant with DiSEqC standards

Comparators Procurement Notes

Verify the specific suffix (e.g., CSA vs. CSAT) against official datasheets to confirm package type and tape-and-reel specifications. Confirm that the component status aligns with project requirements, as this part may be classified as obsolete by the manufacturer. Ensure compatibility with existing PCB footprints before procurement.

Comparators Selection Notes

Select this component when system constraints demand minimal quiescent current alongside precise voltage threshold detection. The built-in reference eliminates external resistor networks, reducing board space. Verify that the 12µs response time meets the application's speed requirements compared to faster comparator alternatives.

Comparators Part Context

This device belongs to the MAX931-MAX934 family of micropower comparators. While the MAX931 offers a single channel, the series includes dual and quad variants. All members share the same low-power architecture and integrated reference capabilities, allowing for scalable designs without changing core component characteristics.

Comparators Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Consult Analog Devices technical support for direct pin-compatible replacements if the MAX931CSA is unavailable.
